New Developments in Non-linear Transport and Magnetism (NLTM)

Non-linear electron transport phenomena in solids, which occur when inversion symmetry is absent, have been widely studied in quantum materials both as fundamental properties associated to wavefunction Berry phases and for device applications in current rectification and frequency doubling. While the breaking of inversion symmetry is usually due to the crystal structure itself, in recent years it has been appreciated that certain types of magnetic order also break inversion symmetry and give rise to new non-linear effects which are magnetically switchable.

In this workshop, leading experts in non-linear transport will be able to share the latest developments in this field. These will include transport effects like DC non-linear longitudinal and Hall effects, as well as optical effects like shift and injection photocurrents and second harmonic generation. The workshop will cover different experimental techniques and a wide range of magnetic, non-centrosymmetric systems, and will have a strong focus on experiment-theory crosstalk and the connection with quantum geometric and topological aspects of such effects.
